摘要

摘要:本文对超临界流体色谱(SFC)快速分析啤酒花的潜力进行了初步研究。以乙醇为流动相，以乙醇改性的二氧化碳为流动相，超声提取7个品种的啤酒花颗粒，用SFC分离。主要萜烯和萜类，以及α和β啤酒花酸，在一次运行中分离。注射到注射的运行时间为13分钟。在目前的发展状态下，这种方法提供了提取的啤酒花样品的快速指纹。对提取方法和色谱参数的改进有望对啤酒花酸和啤酒花油产生更详细的分析信息。

Simultaneous Analysis of Hop Acids and Oils by Supercritical Fluid Chromatography: A Preliminary Study

Abstract A preliminary study was undertaken to establish the potential of supercritical fluid chromatography (SFC) for the rapid analysis of hops. Seven varieties of pelleted hops were extracted in ethanol with ultrasound and separated with SFC using carbon dioxide modified with ethanol as the mobile phase. The major terpenes and terpenoids, as well as the alpha and beta hop acids, were separated in a single run. The injection-to-injection run time was 13 min. At the current state of development, this method provides a rapid fingerprint of an extracted hop sample. Refinement of the extraction procedures and of the chromatographic parameters can be expected to yield more detailed analytical information on both the hop acids and the hop oils.
